Toyota Says System Detects Rear Collisions Before They Happen

Japanese automaker Toyota Motor Corp. said last week that it had developed the world’s first system for detecting rear-end collisions before they happen.

Automakers have already developed systems that warn drivers of head-one collisions. Toyota said in a statement it had developed a radar device, which is installed in the rear bumper to detect a vehicle approaching from behind.

Sensors in the front headrests detects the position of the driver’s and front passenger’s heads, and shifts the position of the headrests to reduce the risk of whiplash injury.
